Abstract

Abstract:

Based on the analyses of the containment system of a new independent type B liquefied natural gas (LNG) carrier, the distribution of temperature field and heat transfer calculation were analyzed in different kinds of conditions using the method of computational fluid dynamics (CFD) numerical simulation. In addition, the boil-off rate under different conditions was calculated. The results show that the evaporation rate of the LNG carrier is increased by 12% compared with that of the intact insulation layer, when the thickness of the insulating layer was 400 mm, the air temperature was 5℃ and the insulation layer is damaged by 1 m². The thermal insulation capacity of insulation materials and the insulation layer damage had great influence on the heat transfer and evaporation rate of LNG cargo hold.

摘要：

以B型液化天然气（LNG）船为对象，通过计算流体力学（CFD）数值模拟方法，分析了不同工况下LNG液货舱的温度场分布以及传热量情况，同时计算了各工况的蒸发率。研究结果表明，在绝热层厚度400 mm、空气温度5℃时，绝热层破损1 m²和绝热层完好的情况相比，其蒸发率增加12%；绝热材料保温能力衰减和保温层破损对LNG液货舱传热量和蒸发率影响较大。
